OIL-BURNER.

SPECIFICATION forming'part of Letters Patent No. 384,275. dated .Tune 12, 1888. Application tiled May 16, 1887. Serial No. QSSAGS). (No model.)

To all whom it may concern..-

Beit known that I, CHARLES H. PHELPS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Burners,of which the fol lowing is such a full, clear, and exact descrip tionoftheinventionaswillenable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming a part of this speciiication, in which similar letters of reference indicate like parts wherever' used.

In said drawings, Figure 1 illustrates a portion of an ordinary cooking-stove to which my newly-invented oil-burner has been attached. Fig. 2 is an enlarged plan View of the burner.

'Fig. 3 is a central vertical sectional view of the same, taken on line 3 3 of Fig. 2, and Fig. 4 is a rear view.

The invention is designed to obviate the many defects present in oil-burners now in use, at the same time to produce a simpler, cheaper, and more durable construction. Among the defects existing in present constructions the greatest is the coking or filling up of the retort, which finally clogs the openings therein and necessitates the repairing of the burner by submitting the retort to a high degree of heat for greater or less periods of time. Another serious objection which my invention is designed to overcome is the fact that heretofore it has been customary to conduct the oil to be burned directly into the retort in a cooled condition, which makes it more difficult to vaporize, and which invites a deposit of those particles or elements of the oil which are only combustible when submitted to great heat. n

My invention consists, essentially, of an outer pipe or retort and au inner pipe provided with proper holes or openings and a draft or relbox surrounding said retort.

In the drawings the retort is lettered A, and the inner pipe B, the lire-box C, and the stove D. The retort A is preferably made round, cast with hollow interior portion, a, and downwardlyprojecting holes or openings a.

The inner pipe, B, is provided on one end with a cap, b, in which is a hole or opening, b',

' on the under side, while the other end of the pipe B is secured in a joint or plug, E, which in turn is screwed into one end of the retort A. The oil-supply pipe e passes through the end of the fire-box C and is screwed into the plug E, thus securely sustaining one end of the re- 4tort in position within the fire-box, as clearly shown in Fig. 3.- The pin e performs asimilar office at the other end Vof the retort. At the rear of the iireebox C an opening, c, is made to admit proper draft to the flame, and the sliding lid c on the top ofthe box makes the exit-opening c2, as shown, which may be increased or diminished, as desired, by sliding said lid c backward or forward.

The' operation of the invention is as follows: The oil isiad mitted through the pipe e (being regulated by means of au ordinary plug valve or cock, not shown) and passes into the pipe B through the small opening b into the Space a, and from thence through the openings a' a to the iire-box, where it is ignited. The draft admitted through the opening c causes the names of the burning oil to find exit through the opening c2, passing around or encircling the periphery of the retort A, and causing said retort to becomehighly heated. In ashort time the pipe B also becomes hot and heats the Iiowing oil, so that when the oil issues from the hole b into the space a it is in a heated state and readily becomes vaporized and issues through the openings a a' as a gas, which is there ignited, as just explained, and which continues to burn until the supply of oil is turned oft'.

I regard it as highly important that the holes or openings 'b' and a a should be made vertical and downwardly opening, as all matter in the oil which might have a tendency to stick and clog the holes if placed in any other position is easily forced out into the tire chamber or box C by the pressure or blast created by the burning oil.

I have shown the retort as Y being placed within the box C; but I do not wish to be limited to such construction, nor tothe particular configuration of the retort or box, as it will be readily understood by those skilled in the art that other forms may be used without at all departing from the spirit or principle 0f loc my invention.

I have also shown my oil-burner as applied to the ordinary cookingstove; but I do not wish to be limited to such use, as it may be used with equal advantage in an open respace, furnaceor the like. I prefer also to extend the pipe B to about the center of the retort A, as shown, and, if preferred, the cap b may be omitted,the end of the pipeB plugged, and the hole b cut near the end ofthe pipe B, instead of in the cap b, as illustrated.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is as follows: er

l. The combination of the retort A, having openings a a', located on the under side thereof, the supply-pipe B, secured therein and having a downwardly-discharge opening, b',

and the box C, having a lid, o', as described, 15 whereby draft-openings may be provided, substantially as specified.

2. The combination of the box C, having a lid, c', and draft-openings c c?, with a retort, A, supported within said box by pins and havzo ing on its under side the openings a a', and a supply-pipe, B, secured within said retort and having a downwardly-discharge'opening, b', at its inner end, substantially asspeeied.
